Interpreting Multiple Regression Output for Business Statistics
Building on our regression model, we add more predictors and interpret the output to see how they improve the model. We begin by checking the assumptions for multiple regression – outliers, normality, homoscedasticity, independence of observations, and multicollinearity – using the output and checks like standardized residuals, Q-Q plot, Durbin-Watson, tolerance, and VIF. Then we add two more predictor to our original model and watch how the parameters change and whether the r-squared change justifies keeping them.
